HSM – Hardware security Module

Data protection for companies and critical infrastructures

Trustway Proteccio™ NetHSM

Bull Trustway Proteccio NetHSM is a Hardware Security Module (HSM) providing software solutions in a high-performance, highly secure environment for performing their most sensitive cryptographic operations.

Optimum security requires a variety of encryption solutions. The Bull Trustway Proteccio range offers multiple products to meet your cryptographic requirements.

High security

Bull TrustWay Proteccio netHSM adds a high-security environment to your Windows, Linux and AIX 32 / 64 bits servers for RSA-ECC-AES cryptographic functions and sensitive custom applications.

Bull cyber Trust compliance


The tamperproof design of TrustWay Proteccio netHSM has been certified under the Common Criteria EAL4+ and FIPS140-2 Level 3 (the later in progress). It encapsulates a Secured-by-TrustWay cryptographic sub-systems allowing you to run security-sensitive processes in a highly performing manner.

Virtual HSM

As cost-sensitive customers, you will be pleased with the competitively priced Bull Trustway Proteccio netHSM family. The advanced virtual HSM capability  featuring 8 HSMs in-the-box provides partners and end customers alike with a very flexible price and performance option.

Certified high security, HSM Trustway Proteccio is designed (hardware and software) , implemented and completely manufactured by Bull in France. CC EAL4+ certification covers hardware and software implementation. FIPS 140-2 level 3 currently in progress..

Virtual HSM, HSM Trustway Proteccio gives access up to 8 virtual HSM simultaneously. Each virtual HSM is a cryptographic partition strongly separated from the others by dedicated encryption keys, users, administrators and auditors. It offers the possibility to share the same HSM between different use cases while keeping the same security level and so getting the most of your HSM and reduce cost.

Manageability and High Availability, supplied with a user friendly application controlled by access right to administrate, configure and manage HSM (security policy, user rights, keys management, HSM configuration and updates). Easy back-up features, save all keys encrypted to be able to restore it. Load balancing features process to secured cryptographic replication and allows high availability. White label – Trustway Proteccio NetHSM is available under white label. It allows to brand it with your identity and logo.
